One object of myin'venti'on isto produce a new and improved lubricated valve Ior gasmeters which will reduce the-present errors in registration of gas consumed. Another object of mydnvention is to provlde'a lubri-j 19 cated valve for gas meters iii-which the lubribodiment oi my invention; reference being cant-is conserved andthe valve will have-Sui ficient' 'lubricationso as not to require attention for alongperiod of time: Another old j'ectof my invention isto prevent or lessen 15 the accumulation uponthe valve faces of residue; which tends to lift the sliding valve member fromits seat;

The crank 28 of the cra-nk 'sha-ft, asshow'n inFig 1, is at its dead center relative to theslide 10,' so that the slide 10' is at tliedimit-ot one ofits I mcvements of reciprocation: The slide member 10 has the u'suai wings 30 and 1 chamber 32.

The outer walls of the reservoirs 34: are so disposed that the lower face of each forward wing 30 is substantially covered by the reservoirs when the sliding members 10 are in their limiting positions, and portions of the outer walls of the reservoirs are always beyond the forward extremity of each wing 30 which results in conserving the lubricant since the moving member on that account- The lower faces of the wings 30, as shown in Fig. 4, are provided with two offset series of recesses 50 which also collect some of the lubricating material delivered from the reservoirs.

In the form shown in Fig.6, the reservoirs for the lubricant are made shallower, as indicated at 52, and the wicking omitted, some of the lubricant rising along the walls of the reservoir and being fed to the contacting surfaces without such wicking. These reservoirs, however, cover the lower faces of the wings so as to provide more continuous contact of lubricating surfaces and provide lubricant supports beyond the edge portion of the wings when at the ends of their movements.

The valve seat and valve, as above dc scribed, are mounted in the ordinary manner and a suitable amount of lubricant is placed in the reservoirs and preferably the recesses in the contacting faces of the valve seat and sliding member are filled with lubricant. As the lubricant in the recesses is-used up, it is more or less replenished by lubricant from the reservoirs, which in operation is automatically spread upon the contacting faces and to some extent collected by the recesses.

The valves as-thus constructed remain lubricated for long periods of time so that no replenishment is necessary practically speaking, except when in the'ordinary course of events the meters are returned to the meter shop for inspection.

In operation, the lubricant itself tends to prevent the accumulation on the valve faces of the gummy residue from the gas and the more continuous contact of the surfaces of the sliding member 10 with a lubricated surface also acts to reduce objectionable accumulation of such gummy residue thereon, and, furthermore, the extremities of the wings 30, as they approach the limits of their 'movement, do not push lubricant beyond the valve seat.

Valves embodying my invention have been found to reduce gas leakage to a substantial extent so as to in the aggregate result in a material saving.

As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof orth-e scope ofthe appended claims.

lVhat I claim is:

1. In a gas meter, the combination of a valve seat having an outlet port and two inlet ports, a winged valve'mcmber sliding thereon, and means for reciprocating said member, said valve seat having lubricant reservoirs situated outwardly from the inlet ports and substantially covering the wings of the sliding member when it is at the ends of its movements respectively.

2. In a gas meter, the combination of a valve seat having an outlet port and two inlet ports, a winged valve member sliding thereon, and means for reciprocating said member, said valve seat having lubricant reservoirs situated outwardly from the inlet ports and having walls ex ending beyond the outer edge portions of the winged member when it is at the ends of its movements.

3. In a gas meter, the combination of a valve seat having an outlet port and two inlet ports, a winged valve member sliding thereon, and means for reciprocating said member, said valve seat having lubricant reservoirs situated outwardly from the inlet ports, and fibrous material within said reservoirs contacting with said sliding valve memberv andacting to apply lubricant to the under surface of the winged valve member.

4. In a gasmeter, the combination of a valve seat having an outlet port and two inlet ports, a winged valve member sliding thereon, and means for reciprocating said member, said valve seat having lubricant reservoirs situated outwardly from the inlet ports and substantially covering the wings of thev sliding member when the sliding member is at the ends of its movements, respectively,said valve seat and sliding member having extending side portions, each side portion'of the sliding memberbeing always in contact throughout its length with the side portions of the valve seat. 7 W I p 5.

6. In a gas meter, the combination of a valve seat having an outlet port and two inlet ports, a winged valve member sliding thereon, and means for reciprocating said member, said valve seat having lubricant reservoirs situated outwardly from the inlet ports and substantially covering the wings of the sliding member when it is at the end of its movement, and the face of said sliding.

member having recesses adapted to collect lubricant supplied from said reservoirs, said recesses in said sliding member comprising two offset series located in each of its wings.

In testimony whereof, I have signed my name to this specification this 20th day of September, 1927.
